This is the same chair that was built for the visit of Benedict XVI to the 2010 exhibition of the Shroud of Turin.
Note the face of the Man of the Shroud on the chair back (click on the chair for a larger view).
And you must watch this video of the chair being assembled to the music, The Charleston composed by James P. Johnson for the Broadway show Runnin Wild. Watch and tap your feet from the 21 second mark until you get bored about a minute later.
Very nice chair. The image can also be found at the altar at the Chiesa del Santo Volto, in Turin, a modern church:
